RECEIVER AND STENCH TRAP.

SPECIFICATION forming part of Letters Patent No. 505,130, datedSeptember 19, 1893. Application filed December 31, 1892.? SerialNil-456,935- (No model.)

To all whom it may concern:

Be it known that I, THOMAS J osnrn RYAN, a citizen of the United States,residing at Buffalo, in the county ofErie and State of NewYork,haveinventedanewandusefulReceiver and stench-Trap, of which thefollowing is a specification.

This invention relates to street receivers and stench traps; and it hasfor its object to provide certain improvements in devices of thischaracter, which are not only adapted for use in connection with drainreceivers, but also in connection with manholes, sewer traps and thelike, so as to provide means for avoiding the accumulation of sedimentwhich clogs the drain, and also to provide for certain adjustments ofthe device in order to accommodate the same to the raising and loweringof grades withoutthe entire removal.

To this end the invention primarily contemplates certain specificfeatures of improvement in receivers and stench traps.

With these and other objects in view which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts, hereinaftermore fully described, illustrated and claimed.

In the accompanying drawingsz-Figure l is a perspective view of acombined receiver and stench trap constructed in accordance with thisinvention and arranged in position at the curb of a street. Fig. 2 is acentral Vertical sectional view thereof. Fig. 3 is an enlarged detailsectional view illustrating the expansion screw joint. Fig. 4 is ahorizontal sectional view on the line 4 4 of Fig. 2, the gate I,removed. Fig. 5 is a detail in perspectiveof the removable valve coverand pressure gate. Fig. 6 is a similar view of the check valve; Fig. 7of the two grate sections separated from each other. Fig. 8 is a detailsectional view on the line y-y of Fig. 2, the valve N,being removed.Fig. 9 is a detail in perspective of the hook rod. Fig. 10 is anenlarged detail sectional view of a portion of the connected pipesections including the locking set screw.

Referring to the accompanying drawings, A represents a tubular orcircular pipe receiver which is provided at its upper end with a doubleset of threads B, arranged at a suitable distance for the purposesherein described, and which are interrupted at regular intervals by thevertical cleaning grooves O, which'provide passages for the fall of dirtor sand which may have accumulated between the threads, and which willbe more particularly described, the sections of threads terminating inabrupt ends 00, at the cleaning grooves, as clearly illustrated.

The pipe receiver A, is contracted at its lower end into a bowl trapD,which is formed by a sharp curve cl, at the lower end of the back Wallof the receiver, and which curve lessens into a broader or fiat curve d,which leads from the bottom point of the pipe at an angle upward to thelower bottom edge of the inclined drain or sewer pipe E, which forms anintegral part of the receiver, and inclines downward therefrom at aslight angle above the plane of the bowl or trap D. The

said bowl or trap D, has the opposite fiat-' tened side walls F, whichserve to form the necessary contraction of the trap in order to providefor the complete flow of the water and sand through said trap and out ofthe drain pipe E.

Directly over the inner end of the sewer drain pipe E, is formed theinclined seat or shoulder Gr, which extends from the lower end of thethreads B, at the same side from which the pipe E, projects, at a sharpangle of about thirty degrees to the beginning of the sharp curve d, ofthe trap, and is provided at its lower extremities with the oppositenotches H.

Arranged to be removably seated on the inclined seat or shoulder G, isthe approximately S-shaped valve cover and pressure gate I. The pressuregate 1, has its opposite edges rest on the opposite portions of saidinclined seat or shoulder, and is provided near its lower end with theopposite supporting shoulders J, which rest in the notches H, at thelower end of the seat or shoulder G.

As clearly shown in the drawings, the S- shaped gate I, does not form acomplete 8, but from the opposite supporting shoulders J, is providedwith a sharply curved pressure tongue K, which is curved or bent on thesame circle as the sharp curve cl, at the bottom of the receiver, andcurvesin close proximity thereto around to a point at about the centerof the trap and in a line with the broader flat curve d, it being seenthat the said tongue together with the straight back wall of thereceiver and the curves of the bottom thereof, forms a contracted fluidpassage through which the water and other fluids must necessarily passunder a concentrated pressure. Another point to be noticed with respectto the pressure gate I, is that the same is not fiat, but on thecontrary is concaved, and deeply so in its tongue, so thatthe water hasno sharp edges to contact, with but has a tubular and approximatelycircular passage through the contraction between the pressure gate andthe receiver. From this construction it will be readily seen that owingto the point to which the lower end of the pressure gate extends, it isimpossible for sand and other sediment to collect in the bottom of thetrap but must necessarily be carried out through the pipe E, under thepressure of the water passing through the contracted trap passage, andthat in said trap is always formed a water seal, which shuts off anyopen passage between the pipe E, and the body of the receiver above thepressure gate.

Within the pipe E, at an opposite angle to .the inner seat or shoulderG, is formed an elongated oval shaped valve seat L, the upper end ofwhich terminates on the seat or shoulder G, at which point, and in said.seat is formed the bearing notches M, for the opposite pivot lugs m, atone end of the oval shaped pivoted check valve N, which is thus arrangedto work over said inclined valve seat and outwardly from the receiver.The check valve N, allows a free passage of the water and sand throughthe pipe E, but on account of the inclination thereof will quickly closeto check any back flow. Eyes 0 are formed at the upper ends of both thepressure gate I, and the check valve N, so that by means of a suitablehook rod, 0, the said gate and valve can be readily lifted out of thereceiver, in order to provide for the easy cleaning thereof. The outwardinclination of the valve seat also allows sediment, &c., to easily slideoff of the same without unseating the valve. The upper threaded end ofthe receiver A, receives the threaded neck of the squared catch basin P.The neck of the catch basin P, is provided with double exterior threadsp, corre .sponding to the double interior threads of the receiver andare set at a"suitable distance apart from each other so that there is aloose thread connection between the two parts, which provides anexpansion joint, allowing a limited vertical play for expansions andcontractions by frost, known as the frost lift, as clearly illustratedin Fig. 3 of the drawings, and it will be noticed that each set ofthreads independently engages the corresponding set of threads of theother section to insure a strong thread connection not easily impaired.The exterior threads of the basin neck are also interrupted at intervalsby the vertical cleaning grooves 19, which together with the grooves O,in the receiver, allow any dirt or sediment between the threads to fallout or drop into the receiver as the basin is adjusted in the receiver,so as to adjust the apparatus to changes in grades without digging upthe entire plant.

At a pointbetween two of the threads of the basin neck,and between twoof the cleaning grooves thereof, is arranged a locking screw Q, havingan inner squared head adapted to receive a five sided socketed key q,for adjusting the screw. It will be seen that when the neck has beenadjusted to the proper height the screw can be turned to project fromthe neck so that it will extend be tween the abrupt terminal ends of theinterior threads of the receiver at the grooves C, so that constantjarring over the basin will not disarrange the connection. When lockedthe cleaning grooves are out of alignment.

From the foregoing it will be clear that the screw Q, by being locatedin a position between two of the threads of the upper pipe section isnecessarily so disposed as to take between the abrupt ends :0 of thethreads of the receiver A at the cleaning grooves, such threads workingin the space in which the locking screw is arranged. In looking theupper pipe section or catch basin, in its adjusted position, suchsection is turned to a position so that one of the cleaning grooves willreceive the outer end of the locking set screw when it is turned, but itwill of course be understood that while the locking screw is projectedsufficiently so as to strike the ends of the thread at both sides of thecleaning groove when the upper pipe section turns, still the said screwdoes not bind on the lower pipe section or receiver whereby the verticalplay or frost lift of the trap would be interfered with. i

The squared basin P, is provided with an interior shoulder R, at thecorners of which are arranged the inwardly extending locking flanges r.A horizontal grate S, rests on a portion of the shoulder of the catchbasin so as to inclose a portion thereof, and is provided with the outernotched corners s, adapted to take under two directly opposite flangesr, so as to lock the front end of the grate, which is further providedat its inner edge with a shoulder s.

Arranged in rear of the inner shouldered edge of the horizontal grate isthe removable curb box T. The curb box T, is arranged at the curb of thegrade in the usual position, and is provided with the notched lockingtongues 25, projecting from opposite bottom edges thereof and adapted toengage the other looking flanges r, at the inner edge of the catchbasin, and res s on the upper edges of such catch basin. The said curbbox is also provided with the inwardly extending screw threaded lug t,projecting downwardly from the top of the box and against which reststhe removable locking grate U; The removable locking grate section U,snugly fits within the open front of the curb box and is provided withthe lower shouldered ends to,

7 adapted to fit the inner shouldered edge of of the horizontal grate.By now forcing the looking grate into the curb box, the horizontal grateand the said curb box are locked firmly in position. A headed lockingscrew V'passes through the countersunk opening of the locking grate, andengages the threaded lug of the curb box to hold the grate sections andthe curb box together, so that they cannot be removed by unauthorizedpersons, but can only be separated by authorized persons having thespecial five sided socketed key q. The five-sided socketed key q, isemployed for removing the screw V,whose head is five sided and whichafter removal allows the removable locking grate section to be taken outfirst, and then the curb box and other grate section.

The combined receiver and stench trap is placed in position at the curbor edge of a grate as clearly illustrated in the drawing and as usual,and it may be here observed that after the removal of the pressure gateand check valve, the entire device can be cleaned in a moment by meansof the suitable hook rod o,illustrated in Fig. 9in the drawings. At thispoint it may be further observed that in order to insure a tight contactof the check valve N, with its seat, I may employ a leather or. rubberpacking washer 1/, arranged on the inclined seat L, as indicated by theheavy line in Fig. 2 of the drawings. It may be further noticed that theloose thread connection between the pipe sections is notonly applicableto receivers and stench traps, but the same provides a constructionwhich is equally as well adapted for stop cock boxes and otherconstructions in which a loose thread connection between the pipesections is an advantage, and in this connection it will be of courseunderstood that there are various kinds of traps, such as sink traps,cellar traps, &c., where it is necessary to use the check valve withoutthe pressure gate, and in such cases by removing the pressure gate I,the device can be readily adapted for these various uses, the

removability of the check valve specially adapting the trap for varioususes.

Changes in the form, proportion and the minor details of constructionmay be resorted to Without departing from the principle or sacrificingany of the advantages of this construction.
